I've been searching the web for the past couple of hours and I cannot for the life of me nail down and answer to a slippery question. My fiance and I would like to start a family in the distant future but we're a little concerned that striking my testicles in any fashion would inhibit that. Is there any literature on the effects of CBT and male fertility easily obtained? The limited information I've found goes both ways. Some places say that the testes can recover from minor to medium hits while others claim that repeated hits, no matter the strength, will lead to infertility. For as important as men make our their balls to be, it doesn't make sense to see almost an absence of information within the BDSM community. I'll freely admit looking in the wrong places, but an hour or two trying to get google to show me what I want is extremely frustrating.
